Method for Manufacturing Wholly Aromatic Polyamide Polymer and Method for Manufacturing Aramide Fiber using The Same

摘要

The present invention relates to a method of producing a wholly aromatic polyester production method of the polyamide polymer and the aramid fibers using the same having a variation in the inherent viscosity ever yet extremely high specific viscosity, the wholly aromatic polyamide polymer prepared by the method of the present invention, the polymerization solvent comprising dissolved to prepare a mixed solution of an aromatic diamine; Preparing the prepolymer by the addition of an aromatic halide diethoxy seed to the mixed solution; And further comprising the step of producing the final polymer by further adding the aromatic halide to the seed diethoxy prepolymer, the prepolymer is characterized in that it is a 1.20 to 2.00 molar ratio of aromatic diamine to an aromatic halide diethoxy seed. ; Polyamide, aramid, prepolymer, NMR, the average mole ratio, intrinsic viscosity
